Description

The Silentnight UltraGel 1400 Mirapocket Mattress delivers firm support with pressure-relieving UltraGel foam and spinal aligning zoned support.

Zoned support

At the heart of this mattress there is a core of 1400 Mirapocket® springs. Encased in their own individual fabric pockets, these springs respond individually. Providing reactive, personalised support based on your movements and weight. Mirapocket® spring units are zoned and firmer in the centre third to provide greater support to your lower back and hips. This can promote better spinal alignment and help to ease aches.

Foam layers

A 3cm layer of UltraGel™ foam quickly adapts to your unique shape, embracing you in instant comfort. The gel is designed to help evenly distribute your weight and lift it off your pressure points. Resulting in rejuvenating pressure relief for a comforting sleep. This foam allows you to move freely across the mattress without sinking in too deep. Providing a relaxingly comfortable sleep environment night after night.

Followed by a 2cm layer of reflex foam to enhance the comfort of this mattress further. Reflex foam is a durable material that can enhance longevity for longer use.

Breathable design

UltraGel™ foam is made with an open cell structure to encourage breathability. It has been tested and proven to be 5 times more breathable than standard memory foam. Delivering a fresher, cooler feel for a comforting rest.

The mesh fabric border encourages greater airflow within the mattress. This can decrease the build up of heat and moisture for a fresher, cleaner sleep environment. Extending the lifespan of the mattress.

Layers of soft white fibres increase the breathability of the mattress further by encouraging greater airflow through the interior. The top layer of soft white fibres is plush and cosy for comforting cushioning. The additional layers are densely packed for added durability, helping to keep your mattress in good shape.

Firm mattress

Rated firm, this mattress is ideal for those who prefer that study, firmer feel. The tufted finish secures the mattress layers in place, enhancing durability. This tufted technique also helps to enhance the firmness of the mattress.

Maximised sleep space

Designed with a sturdy rod edge which means there are durable rods placed across the top and bottom of the spring unit. This feature makes the edge of the border firmer so you can sleep right to the very edge without the 'roll-off' feel.

Decades of experience

As one of the first B-Corp certified sleep brands, Silentnight have proven why they are the UK’s most trusted name in sleep. Their commitment to quality and environmentally responsible practices ensures a better night’s rest and a brighter future for you.

Made in the UK, you can rest assured this mattress has met the highest standards for quality and safety. Enjoy the security of the 5 Year Guarantee which protects you against any manufacturing faults should they occur.

Please note: pocket spring count is based on a kingsize mattress
